Bathylogger BL230 Dual Frequency Echo Sounder

The BL230 is both a Survey Grade 200 kHz and 30kHz echo sounder in one transducer and is the best choice for shallow water bathymetric (hydrographic) surveys up to 200 meters deep. The 200 kHz is used for up to 100m of water depth and the more powerful 30 khz is best from 100m – 200m of water depth. Dredgers also like using them to determine hard or soft bottom. By seeing how far the 30 khz penetrates compared to the 200 khz top layer return. This model comes in a DB9 RS232 or a USB data output connector.
